Kevin Coster, who starred opposite Whitney Houston in the 1992 smash ‘The Bodyguard,’ will speak at Houston’s funeral this coming Saturday, according to PEOPLE.

The movie, which was Houston’s first starring role, was a mega-hit, earning more than $400 million at the box office internationally. Its soundtrack sold a staggering 42 million copies worldwide and spawned five hit singles, including Houston’s signature song ‘I Will Always Love You.’

Houston’s longtime mentor Clive Davis will also speak and Aretha Franklin and Stevie Wonder will sing at a private ceremony held in Houston’s hometown of Newark, New Jersey. Houston’s ex-husband Bobby Brown, Oprah Winfrey, Tyler Perry, Alicia Keys and Dionne Warwick are expected to attend as well.

Houston was found dead in a Beverly Hills, California hotel room on Feb. 11. Cause of death is still pending investigation by police. She was 48-years-old.
